Sorry to contradict you, Stuart, but capitalization is definitely NOT important. Formulas and conditions (and layout tokens) are case-INsensitive, so UPPER or lower or MiXeD cases all mean the same thing (internally, the whole thing is converted to lowercase during processing).
Also, your example is correct, but I want to point out that including state = 2 will actually make the event more restrictive. That might be what you want in the end, but I wanted to make clear that this makes it so the event will fire only during the tournament, not before the tournament or during a countdown or after the tournament is over. Again, that may be what you want. It's just that when I'm trying to figure out why an event isn't firing when I think it should, I usually make things less restrictive until I get it to fire, and then start adding the restrictions in until it no longer fires when I think it should, in order to figure out what I've got misconfigured.
